Hermosillo, 
Mexico
765,445 people lived in Hermosillo in 2025. It is the 698th largest of the world's 12,138 cities, and the 16th largest in Mexico.
Like every city on this site, Hermosillo is counted as a built-up area seen from above rather than as a city government's territory. Why that changes the number.

How to read this: read it left to right, 1975 to 2050, one column every five years, the height being people. Hatching marks the projected years. Below, a strip of the UN's confidence: strong colour where the census maps are recent and detailed, pale where they are not, blank where the place was not counted as a city.

Where it is
How to read this: every dot is one of the 186 cities in Mexico in 2025, and a dot's area is how many people live there, the biggest being Mexico City. The ringed dot in colour is Hermosillo; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Hermosillo covered 158 km², and buildings, roads and other built-up land covered 48 km² of it. That is 62 m² of built-up land for each person, about a square 8 by 8 metres. Since 1975, its built-up land has grown to 5.6 times its size, and its people are 5.6 times as many.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in Mexico
Its share of Mexico
Of every 1,000 people in Mexico in 2025, 6 lived in Hermosillo, which is 765,445 people.
How to read this: shrink Mexico to 1,000 people and this is what you get. The coloured squares are the ones who would live in Hermosillo; the grey ones are everybody else, in other cities, in towns and out in the country.

How to read this: the number before each name is its place among all 12,138 cities in the world in 2025; bars are people, on one scale per list. Only cities that reach 300,000 people have a page here, so a gap in the numbers is a smaller city.
Apparatus
Sources and method
The figures for Hermosillo are the UN's own, at five-year steps: an estimate for each of 1975 to 2025, then projection to 2050. Projected years are drawn hatched, and the UN publishes no range of uncertainty for a city. What a city means here, how the UN measures one, and why that number can differ from the one Hermosillo publishes about itself: how the figures here are put together.
